I'm thinking .25-20 as I already have a Remington 25 in that caliber.

I'm really getting worried about my Martini addiction. I just bought another one rechambered to 32 Special, aperture rear sight and ramp front sight, new bluing, and it has been restocked in really, really good curly maple. Curly maple is my other addiction, so I couldn't very well pass this gun, could I?
